Staff Software Engineer, Mobile (P2P / Fiat)
Location: Hong Kong, Hong Kong SAR
Department: Engineering
Who We Are
About The Opportunity
We are looking for a Staff Mobile Engineer to join our P2P & Fiat team, where you will own the mobile engineering for OKX's crypto fiat on/off-ramp experience across offshore and international markets. This is a high-ownership role at the intersection of mobile engineering and cross-border payments — you will build and scale the end-to-end fiat-to-crypto conversion journeys that serve users across Southeast Asia, LATAM, MENA, and beyond.
You bring hands-on experience building crypto on/off-ramp products, deep familiarity with cross-regional fiat payment integrations, and the technical discipline to own complex, multi-step transaction flows in a consumer-facing mobile product. You are also fluent in AI-assisted development and bring the rigour to build, maintain, and continuously improve your own AI engineering workflows.
What You'll Be Doing
- Own the mobile engineering for the crypto fiat on/off-ramp experience — including quote flows, payment method selection, transaction status, and failure handling end-to-end.
- Build and maintain cross-regional fiat payment integrations — including local bank transfers, e-wallets, and third-party PSP integrations across markets such as Southeast Asia, LATAM, and MENA.
- Ensure mobile payment flows and user data handling are compliant with offshore crypto market requirements — including KYC tiers, transaction limits, and regional regulatory constraints.
- Collaborate closely with compliance, legal, product, and regional market teams to translate local regulatory requirements into reliable, user-friendly mobile experiences.
- Drive technical decision-making on payment architecture, articulating trade-offs clearly across speed, maintainability, and compliance.
- Apply AI coding tools actively in your workflow — not just for code generation, but to build and maintain repeatable personal AI development workflows.
- Mentor engineers on the team and contribute to a culture of ownership, technical rigour, and high engineering standards.
What We Look For In You
- 5+ years of native iOS or Android development experience, with a track record of owning high-stakes, multi-step transaction flows in consumer-facing mobile products.
- Hands-on experience building crypto token on/off-ramp products targeting offshore or international markets.
- Deep familiarity with cross-regional fiat payment integrations — local bank transfers, e-wallets, and third-party PSPs across markets such as Southeast Asia, LATAM, or MENA.
- Strong understanding of the full fiat-to-crypto conversion UX — quote flows, payment method selection, transaction status, and failure handling.
- Aware of compliance considerations in offshore crypto markets — KYC tiers, transaction limits, and regional regulatory constraints.
- Proficient in AI-assisted development — deep hands-on use of Claude Code, Codex, or equivalent code models in daily workflow, with the ability to independently build and maintain a personal AI development workflow including prompt engineering, toolchain integration, and agentic coding.
- Strong cross-functional communication — comfortable working with compliance, legal, product, and regional market teams to hold the line on engineering quality.
Nice-To-Haves
- Experience in high-growth emerging markets where fiat accessibility is a key driver of crypto adoption.
- Experience integrating with specific PSPs or payment rails commonly used in Southeast Asia, LATAM, or MENA markets.
- Familiarity with anti-fraud mechanisms in P2P or fiat payment contexts.
- Experience operating across multiple regulatory environments simultaneously.
- Background in fintech, crypto, or regulated consumer financial products.

Competitive total compensation package
-
L&D programs and Education subsidy for employees' growth and development
-
Various team building programs and company events
-
